Data Domain: How to power-off and move a DD system

How to correctly power off and move a Data Domain System.

Applies to:

• All Data Domain systems
• All Software Releases

System and attached storage must be shut down gracefully before being moved to a new location.

Using the DD-CLI as an Admin user; follow the procedure below to move a Data Domain system, including expansion shelves, to another location.

1. Check for and address any outstanding Alerts

   # alerts show current

2. Disable replication

   # replication disable all

3. Disable any Remote Logging

   # log host disable

4. Issue the following CLI command. This gracefully shuts down the filesystem and powers off the system controller.

   # system power-off

   Wait for the controller to power off completely

5. Power off each expansion shelf by removing the AC Power cables.
   

6. Remove the system, storage, and cabling from the rack

7. Move the system to the new location and rerack all the components.

8. Power on each shelf by connecting the AC power cables.

9. Wait 2 minutes after the final shelf was powered on, then restart the system (controller) by pressing the power button on the front panel.

10. Verify the shelf connectivity. After the system boots up, run the following command, ensuring all the connected enclosures are reported by DD OS.

    # enclosure show all

11. Verify that the Filesystem is 'Enabled and Running'

    # filesys status

12. Once the new IP address is configured in the system, test connectivity to and from the partner DDR by using the following command from both systems.

    # net ping < hostname-partner>

    Additional network configuration may be required in the new location (beyond the scope of this KB article).

13. Enable replication from the partner system using the following command

    # replication enable all

14. Enable Host logging if needed

    # log host enable
